Method for rapidly grafting green pomelo

Abstract

The invention discloses a method for rapidly grafting a green pomelo. The method comprises the following steps that tender stems with internodes are selected as explants, are disinfected and then areinoculated to a cluster bud inducing culture medium for culture, calluses are transferred to subculture so as to obtain subculture adventitious buds and finally are transferred to a rooting culture medium for culture, rootstock tissue culture seedlings are obtained after rootage, and then field planting is carried out on the tissue culture seedlings in a seedling culture substrate for culture so as to obtain rootstocks; semi-lignified green pomelo branches with good growth are selected as scions, before grafting, the scions are firstly put into a disinfectant for disinfection, and then the scions are grafted onto the rootstocks by adopting a conventional cut grafting method and then are wrapped with plastic films; and after grafting, seedling management is carried out. The method has the advantages that the green pomelo seedlings obtained by grafting can guarantee the excellent variety characteristics, the survival rate of the grafted fruit seedlings can reach 98% or above, in addition, the operation is simple, the cost is low, the grafting time is obviously shortened, the application prospect is wide, and a powerful technical support is provided for accelerating the rapid development of the green pomelo industry.

Description

technical field [0001] The invention belongs to the technical field of nursery stock propagation, in particular to a method for quickly grafting green pomelo. Background technique [0002] Green pomelo, also known as emerald pomelo, is native to the lowland area near Bangkok, Thailand. It is short spherical in shape, with pink flesh and a small core. . Green pomelo pulp is crystal clear, crisp and tender, with thin skin and thick flesh. The edible rate is over 80%. It is juicy and seedless. Green pomelo fruit can be stored at room temperature for 2-3 months after being harvested. It does not change color, taste or rot. It will drop fruit and have better quality, so it has the reputation of "natural canned food". The weight of a single fruit is generally about 2.5 catties, and the large one can reach 5-6 catties. The 2-year-old tree can produce 30-50 fruits per plant, and the yield per mu can reach 3000-4000 catties; the 3-year-old tree can bear fruit per plant. 50-80 fru...

Problems solved by technology

[0005] When it is high, it can be planted in separate beds or moved into nutrition bags, and it can be planted after 1 year of cultivation. This method not only slows the propagation speed, but also is difficult to maintain good traits

Grafting and propagation can ensure that the offspring maintain the excellent traits of the mother tree. At present, the seedlings obtained by sowing are mainly used as rootstocks. After the seedlings grow to a certain height, they are grafted with the scion. This method has slow propagation speed and high cost
